HOW TO CREATE A SIMPLE DB-TREEVIEW ================================== Delphi 2.0 only Author: Alexander Halser EMail: halser@easycash.co.at Net: http://www.easycash.co.at THIS EXAMPLE IS FREE. USE IT ON YOUR OWN RISK ! Comments are welcome to! PURPOSE ------- There are a few "TDBTreeViews" on the internet now. Most of them are shareware and - this is the reason why I wrote this - didn't work like I had expected. Some are very powerful but need a complex data structure to work. Of course, a REAL DBTreeView is more comfortable. This Example shows you how to make a simple TreeView behave like a DBTreeView. It uses a the CUSTOMER.DB from Delphi DBDEMOS and sorts it with "Country | State | Customer". Check out the PROJECT1. INSTALLATION ------------ None. USAGE ----- The enclosed example uses the unit TREEFUNC.PAS. In TREEFUNC.PAS are some functions and procedures which helps the item navigation. Copy TREEFUNC.PAS into your Delphi libary and add a pointer to the uses... list of your new project.
